DESCRIPTION OF SOFTWARE FEATURES
The switch provides a wide range of advanced performance enhancing
features. Flow control eliminates the loss of packets due to bottlenecks
caused by port saturation. Storm suppression prevents broadcast,
multicast, and unknown unicast traffic storms from engulfing the network.
Untagged (port-based), tagged, and protocol-based VLANs, plus support
for automatic GVRP VLAN registration provide traffic security and efficient
use of network bandwidth. CoS priority queueing ensures the minimum
delay for moving real-time multimedia data across the network. While
multicast filtering provides support for real-time network applications.
Some of the management features are briefly described below.
CONFIGURATION
BACKUP AND
RESTORE
You can save the current configuration settings to a file on the
management station (using the web interface) or an FTP/TFTP server
(using the web or console interface), and later download this file to restore
the switch configuration settings.
IEEE 802.1D Bridge Supports dynamic data switching and addresses learning
Store-and-Forward
Switching
Supported to ensure wire-speed switching while eliminating bad
frames
Spanning Tree Algorithm Supports standard STP, Rapid Spanning Tree Protocol (RSTP), and
Multiple Spanning Trees (MSTP)
Virtual LANs Up to 4094 using IEEE 802.1Q, port-based, protocol-based,
voice VLANs, and QinQ tunnel
Traffic Prioritization Default port priority, traffic class map, queue scheduling, IP

Connectivity Fault
Management
Connectivity monitoring using continuity check messages, fault
verification through loop back messages, and fault isolation by
examining end-to-end connections (IEEE 802.1ag)
ERPS Supports Ethernet Ring Protection Switching for increased
availability of Ethernet rings (G.8032)
Remote Device
Management
